XLS files are binary spreadsheets that require Excel or compatible software to open. Converting XLS to CSV extracts the raw cell data as plain text, making it immediately consumable by databases, ETL pipelines, data science tools, and legacy import utilities.
Our XLS to CSV converter uses xlsx2csv to read the Excel binary format and export each sheet's cell values as comma-separated text. Single-sheet workbooks produce one CSV file; multi-sheet workbooks produce multiple CSVs in a ZIP archive.
CSV is the simplest and most universally understood data exchange format. After converting from XLS to CSV, your data can be imported into any database or processed by any programming language without installing any spreadsheet software.
CSV strips formatting, formulas, and metadata — only computed cell values are retained. Cells containing dates should be in a consistent, unambiguous format (e.g. ISO 8601: YYYY-MM-DD) to prevent interpretation errors in downstream systems.
